Embodiment Construction
[0017] The energy-collecting permanent magnetic levitation device of the present invention is used on the suspension rail magnetic levitation road-vehicle, and the energy-collecting permanent magnetic levitation device comprises two parts: a groove base and a permanent magnet group, wherein:
[0018] Groove base: It is composed of the bottom of the groove and the wall of the groove. Made of ferromagnetic metal (such as carbon steel Q235). The groove bottom and the groove wall are flat and smooth, and the two groove walls extend parallel to the longitudinal direction.
[0019] Permanent magnet group: Composed of permanent magnets symmetrically from the center to the outside: two main permanent magnets are in the center, and a non-ferromagnetic inlay is sandwiched between the two main permanent magnets. The N pole of one main permanent magnet is upward, and the N pole of the other main permanent magnet is downward (the notch is upper, and the groove bottom is lower). The two s...

The invention discloses an energy-saving permanent magnet suspension device. The lower sides of two ends of a suspension power bay are respectively provided with an energy-collecting permanent magnet wing, and the upper sides of two ends of an arched suspending pillow are respectively provided with an energy-collecting permanent magnet track; the energy-collecting permanent magnet wings and the energy-collecting permanent magnet tracks are all comprises chute bases and permanent magnet groups, the chute bases are integrally made of ferromagnetic material, and two chute walls longitudinally extend in parallel; the permanent magnet groups are made of hard magnetic material and embedded in the chute bases, and a nonferrous magnetic inlay is clamped between two permanent magnets; the N pole of one of the permanent magnets is upward, and the N pole of the other permanent magnet is downward; two side permanent magnets are respectively arranged among a main permanent magnet and the chute walls of the chute bases, the N pole of the side permanent magnet at one side of the main permanent magnet with the upward N pole faces to the main permanent magnet, and the S pole faces to the chute walls, the N pole of the side permanent magnet at one side of the main permanent magnet with the upward S pole faces to the outside of the chute walls, and the S pole faces to the main permanent magnet; and the energy-collecting permanent magnet wings at the lower sides of two ends of the suspension power bay and the main permanent magnet in the energy-collecting permanent magnet tracks arranged on the upper sides of two ends of the arched suspending pillow are aligned with each other at the same poles and arranged up and down.
Description
technical field [0001] The invention belongs to the technical field of permanent magnetic levitation, and in particular relates to a permanent magnetic levitation device technology composed of permanent magnetic levitation rails and permanent magnetic levitation wings. Background technique [0002] One of the levitation force sources of levitation devices such as permanent maglev trains is the repulsive force generated by the corresponding magnetic poles between the rail permanent magnets installed on the track and the car permanent magnets installed on the train. A non-ferromagnetic interlayer is provided between the two permanent magnets of the N pole and the S pole of the energy-collecting permanent magnet levitation wing on the existing energy-collecting permanent magnet track and the train and the ferromagnetic groove wall. Although this method effectively increases the levitation force, it also wastes the space of the ferromagnetic groove, and is not conducive to the f...
